Transaction Reconciliation

What is Transaction Reconciliation?

Transaction reconciliation is the process of matching individual transactions recorded in one system against corresponding records in another—such as matching payment remittances against open invoices, or matching bank transactions against general ledger entries—to verify completeness and accuracy.

Transaction reconciliation is foundational to both the financial close and the invoice-to-cash processes. BlackLine's platform automates transaction matching at scale, using AI to handle high-volume, complex matching scenarios—such as many-to-one and one-to-many payment applications—and routing only genuine exceptions to human reviewers.

What Are the Different Types of Transaction Reconciliation?

There are many types of transaction reconciliation including:

  • Bank reconciliation is the process of reconciling bank transactions such as deposits, withdrawals, checks, automatic payments, and electronic debits. The business will reconcile its own transaction records with the statements it receives from the bank.

  • A vendor reconciliation compares transaction records provided by a vendor or supplier with the business’s own accounts payable ledger.

  • Intercompany reconciliation is the process of reconciling statements and transactions between units, divisions, or subsidiaries of the same parent company.

  • Business specific reconciliation involves the reconciliation of transactions in a specific business unit, such as a stock inventory or expenses reconciliation.

  • Petty cash reconciliation is the process of verifying that all transactions in the petty cash fund are correct.

  • Credit card reconciliation compares purchase receipts with credit card statements provided by the card company.

How is Transaction Reconciliation Performed?

Reconciliation can be performed in one of two ways:

  1. A business can perform transaction reconciliations by reviewing documents. This is done by examining transactions in the business’s own financial records and comparing those with source documents, such as receipts, invoices, or statements.

  • A business can also perform transaction reconciliation by doing an analytics review. This is done by performing a historical analysis and comparing this to current data. If present transaction entries are widely different from projections made from historical data, this may be a sign of irregularities.
